REFRIGERATOECABINET STRUCTURE.

Application filed March 2, 1928. Serial N0. 258,577.

My invention relates to refrigerator cabinet structure and it is an object of the invention to provide a simple, strong, and durable construction having better insulating qualities resulting in increased efiiciency, all as will be hereinafter more particularly described and claimed.

' Referring to the accompanying drawings which are made a part hereof and on which similar reference characters indicate similar parts,

Figure 1 is a front elevation of a refrig erator cabinet constructed in accordance with my invention,

Figure 2,- a section on the line 2-2 of Fig. 1, I

Figure 3, a section on the line 33 of Fig. 1,

Figure 4, a detail perspective of the end or a cross rail and Figure 5 a detail perspective of the end of the upright center pillar.

in the drawings reference character 10- indicates a refrigerator cabinet adapted to be used with an automatic refrigerating unit and having a metal exterior provided with an enamel or porcelain finish and with an interior of similar construction or of plain galvanized metal.

The walls of the cabinet are formed of suitable insulating material and in the present instance i provide an upright center column or pillar and a cross column or rail or simple construction which includes inner and outer metal casings and a cork or other insulating tiller. The center pillar, a section of which is shown in Fig. 2, comprises an elongated U shaped sheet metal channel member 11 which serves as the exterior of the pillar or column and has a filler of compressed cork 12 covered with a sheath of insulating paper or the like 13. This construction'provides a column of durable construction and of suiiicient strength to withstand continued closing of the: doors of The inside of the column orthe cabinet. pillar is provided with a shallower sheet metal channel member 14 which has its side edges turned outwardly to form lips or flanges 15. I

In order to prevent the conductivity of heat from one channel member to the other they are preferably secured with their contiguous edges in spaced relation. The channcl members 11 and 14 are held together at each side of the column by means of a stri of wood molding 16 having a saw kerf 1 into which the lip or flange 15 projects. This wood molding is held in place by machine screws 18 threaded into a sleeve 19 which extends through the center of the column and serves to prevent the collapsing of the same when the screws are tightened. Since the sleeve 19 extends throu h the channel member 11 the bolt 18 and 11p or flange 15, being engaged and held together by means of the strip or wood molding 16, will hold the channel member in proper shape.

The extremities of the center column are formed as shown in Fi 5 with the bottom of the channel turned under to'form an end plate 20. The side members are provided with integrally formed outwardly turned extensions 21 across all of which a strip 22 is fastened by means of spot weld ing or the like, holes 23 being provided at the extremities of the strip for the reception of screws 24 for holding the column in position.

A cross rail or cross column is provided formed of a relatively deep U-shaped chanshapcd channel member 26 provided with outwardly turned lips 27', thechannel members 25 and 26 being of substantially the same construction as the channel-members l1 and 14; respectively and being held vtogether in a like manner. The outer end of the cross rail or column is formed in a manner similar to the lower end of the center column and is secured in a like manner. The end of the cross column which connects to the center column is illustrated in Fig. 4.

in which the body of the column is turned over to provide an end portion 28 which along with integral side portions 29 complete the structure of the end of the member, the portions 28 and 29 being preferably .nel Inember 25 and. a relatively shallow U spot welded to the sides of the U-shaped lit will be understood of course that this construction may be used for any size cabinet or for an number of doors and can be provided wit any desired finish as porcelain, enamel, lacquer, paint, or the like.

It will be obvious to those skilled in the art that various changes may be made in my device without departing from the spirit of the invention, and I, therefore, do not limit myself to what is shown in the drawings and described in the specification, but only as set forth in the appended claims.

Having thus fully described my said invention, what I claim as new and desire to secure by Letters Patent, is:

l. A refrigerator cabinet structure comprising a frame member formed of apair of opposed channel members, a filling of insulating material, and a molding strip fastening said channel members together, substantially as set forth.

2. A refrigerator cabinet structure comprising a frame member formed of a pair of opposed sheet metal channels, one of said sheet metal-channels having its ed es turned outwardly to form flanges, a molding strip receiving one of the flanges, and a screw extending through the molding strip and into the members together, substantially as set forth.

3. A cabinet structure for a refrigerator comprising a channel member, an opposed channel member, said channel members having their contiguous edges disposed in spaced relation, and a molding strip securing said channel members in fixed relation, substantially as set forth.

4:. A cabinet structure for a refrigerator comprising a channel member, an opposed channel member, said channel members having their contiguous edges disposed in spaced relation, and a molding strip securing said channel members in fixed relation, one of said channel members having its mid-portion turned over to form an end and having side portions turned outwardly to form securing feet, substantially as set forth.

5. A cabinet structure for a refrigerator com risin a channel member an o osed' feet, and a cross bar connecting said securing feet and extending across said end and spot welded to the end and feet to form an integral structure, substantially as set forth.

6'. A refrigerator cabinet construction comprising a frame member formed of a body of insulating material, an insulating sheath covering said body, a channel member extending on three sides of the body, a second channel member disposed in opposed relation thereto,v and a longitudinally arranged molding strip fastening said channel members in fixed relation to form arigid post structure having its'opposite surfaces covered with metal, substantially as set forth. i

7. A joint comprising a pair of metal plates disposed in substantially the same parallel plane, one of said plates being provided with a projection thereon, and a molding strip engaging said projection and be- .ing fastened to the other plate for securing the lates in fixed relation, substantially as set orth.

In witness whereof, I have hereunto set my hand at Connersville, Indiana, this 27th day of February, A. D. nineteen hundred and twenty-eight.
